Detailed Description

Stateless decoder for NIfTI-1 single-file volumes (.nii and .nii.gz).

Parses the 348-byte fixed-size header, expands any voxel-type / endianness combination NIfTI-1 supports into the canonical 16-bit unsigned slice buffer produced by MriMghIO, and resolves voxel\u2192RAS via the sform/qform/pixdim priority chain. The class is a pure namespace of static methods so callers can use it without owning any state; the populated MriVolData carries the result.

Member Function Documentation

decompress()

bool MriNiftiIO::decompress ( const QString & gzFile, QByteArray & rawData )

static

Decompresses a .nii.gz file into rawData.

Exposed for direct use by tests; read calls it transparently when the input path ends in .gz.

Parameters

[in]	gzFile	Path to the gzip-compressed input.
[out]	rawData	Output buffer.

Returns

True on success.

Definition at line 104 of file mri_nifti_io.cpp.

read()

bool MriNiftiIO::read ( const QString & niiFile, MriVolData & volData, bool verbose = false )

static

Reads a NIfTI-1 single-file volume.

For .nii.gz inputs the file is decompressed in memory via zlib (re-using the same MAX_WBITS+16 strategy as MriMghIO).

Parameters

[in]	niiFile	Path to the .nii or .nii.gz file.
[out]	volData	Volume to populate.
[in]	verbose	Print header geometry on success.

Returns

True on success, false on parse / I/O error.
